MR. JO JR 3017: Aromatic Reactive Diluent Modified Epoxy Resin

Introduction

When formulating high-performance adhesives, self-leveling floors, grouts, or mortars, the biggest challenge is balancing workability with strength and chemical resistance. Standard bisphenol-A resins often need external diluents to reduce viscosity, but these can compromise toughness, adhesion, or resistance. JPOXY JR 3017 is designed to solve...

MR. JO JR 3016: Modified Epoxy Resin for Adhesives, Topcoats & Flooring

Introduction Formulators striving for high performance in adhesives, flooring, or clear topcoats often face compromises: either add diluents or reactive modifiers after purchase (which introduces variability), or settle for a resin that’s simply too viscous. JR 3016 is engineered to remove this compromise. A bisphenol-A epoxy...

MR. JO JR-3013: Low-Viscosity Modified Epoxy Resin for Tile Grouts, Primers, and Coatings

Introduction In the formulation of primers, coatings, and tile grouts, viscosity control is one of the most critical parameters. Unmodified bisphenol-A (BPA) epoxy resins provide excellent adhesion and durability but are typically too viscous for thin-film or highly filled applications. This leads formulators to rely on...

MR. JO JR 3012: Modified Epoxy Resin for Coatings, Primers, Mortars, and Flooring

Introduction As industries continue shifting toward high-solids, solvent-free, and environmentally compliant epoxy systems, formulators need liquid resins that offer both low viscosity and high versatility. Unmodified bisphenol-A (BPA) resins deliver excellent adhesion and durability, but their viscosity often limits solids loading and ease of processing. JR 3012...

MR. JO JR 3011: Modified Epoxy Resin for High-Solids Coatings and Waterproofing Applications

Introduction In modern industrial applications, formulators are often faced with a trade-off: balancing processability with performance. Conventional unmodified bisphenol-A epoxy resins such as JPOXY JR 3000 or JR 3010 deliver excellent mechanical and chemical resistance, but their relatively high viscosity can pose challenges in high-solids formulations,...

MR. JO JR 3010 — Lower-viscosity unmodified epoxy resin for better wetting and easier dilution

JR-3010 is an unmodified BPA epoxy resin with EEW 180–188 and viscosity 8,000–11,000 mPa·s. It sits below JR 3000 in viscosity: an attractive option where degassing, pumpability and lower need for diluent are priorities — yet it still provides a predictable EEW baseline comparable to...

JR 3000 vs JR 3001 vs JR 3003 vs JR 3125 — which unmodified epoxy resin should you use?

When engineers, formulators and shop managers pick an unmodified epoxy resin they’re solving a set of practical problems: matching viscosity to the process, getting the required optical clarity, tuning cure behavior via an appropriate hardener, and minimizing waste and handling issues on the shop floor....

MR. JO JR-3125 — Very-high-viscosity unmodified epoxy for adhesive formulators (revised)

Technical snapshot Type: unmodified BPA epoxy resin (resin-only) EEW: 200–250 g/eq (reactive backbone for formulators) Viscosity: very high (formulator grade — significantly thicker than JR-3003) Packaging: 10 / 20 / 30 kg packs and barrels; long shelf stability in company packaging

The real problem adhesive makers face

Adhesive manufacturers don’t...

MR. JO JR 3003 — High-Viscosity Unmodified Epoxy for Adhesives & Decoupage Coatings

Technical snapshot Type: Unmodified BPA epoxy resin (resin-only) EEW: 200–230 g/eq Viscosity: 20,000–40,000 mPa·s (high) Packs: 10 / 20 / 30 kg and barrels; long shelf stability

Primary problem addressed

Many adhesive and decorative coating tasks require body — the ability to stay where applied, bridge gaps and avoid sag...
